Application of the AgNOR method to cell imprints of lymphoid tissue

Abstract
The argyrophil (AgNOR) staining technique for nucleolar organizer regions was applied to both cell imprint preparations and 3 μm sections of 40 specimens of lymphoid tissue (10 normal tonsil, 10 reactive follicular hyperplasia, and 10 low‐grade and 10 high‐grade non‐Hodgkin's lymphomas). The mean AgNOR count per nucleus was higher for imprint preparations than for 3 μm sections for each group of specimens (PPabsolute rather than relative AgNOR counts.
